[0011] Preferably, the auxiliary adjustment collar is connected with a hinge groove, the top of the audio collector is connected with a shaft rod in cooperation with the hinge groove, and the auxiliary adjustment collar is connected with a shaft actuator in cooperation with the shaft rod.

[0012] Preferably, there is an angle ∠α between adjacent audio collectors on the guide rail, and the range of ∠α is 15° to 45°.

[0013] The advantages of the present invention over the prior art are: in the present invention, a plurality of guide rails and audio collectors connected to the guide rails can cooperate to collect the sound source in an all-round manner, and the number of guide rails can be adjusted as needed, which is also convenient for adjusting the number according to different sound collection needs. In order to ensure the audio position in the present application, the sound source can be positioned by an additional positioning rope to ensure that the sound source is collected in the middle of the device;

[0014] For ease of use, an axis actuator and a stepper motor are additionally provided in this application, which can not only adjust the position of the audio collector, but also adjust the inclination angle of adjacent audio signals as needed to simulate body obstruction.
